IPv6 Test Lab Extension: Demonstrating DNS Zone Transfers over IPv6

This IPv6 Test Lab Extension describes how to configure and demonstrate a DNS zone transfer over IPv6. You configure DC1 to allow a zone transfer for the corp.contoso.com domain to APP1’s IPv6 address, configure APP1 as a DNS server, configure the corp.contoso.com as a secondary domain from DC1’s IPv6 address, and then show the results of the zone transfer.

Note These instructions are designed for a working IPv6 test lab that has been configured based on the instructions in the Test Lab Guide: Demonstrate IPv6.

If you are running the IPv6 test lab in a virtual environment, you can create snapshots of the virtual machines (VMs) for all of the test lab computers before performing the following procedure.

Configuring and Demonstrating DNS Zone Transfers over IPv6
To configure DC1 to allow zone transfers to APP1’s IPv6 address:

On DC1, click Start, point to Administrative Tools, and then click DNS.
In the console tree, open DC1, then Forward Lookup Zones, right-click corp.contoso.com, and then click Properties.
Click the Zone Transfers tab, click Only to the following servers, and then click Edit.
In Allow Zone Transfers, click <Click here to add, type APP1 and then press TAB. The wizard displays both the IPv4 and IPv6 addresses of DC1.
Click the 10.0.0.3 address, click Delete, and then click OK twice

To configure APP1 as a DNS server:

From the console tree of Server Manager, click Roles.
In the details pane, click Add Roles.
On the Before You Begin page, click Next.
On the Select Server Roles page, click DNS Server, and then click Next.
On the DNS Server page, click Next.
On the Confirm Installation Selections page, click Install.
On the Installation Results page, click Close.

To create a secondary zone for corp.contoso.com on APP1 and demonstrate the zone transfer from DC1:

On APP1, click Start, point to Administrative Tools, and then click DNS.
In the console tree, open APP1, right-click Forward Lookup Zones, and then click New Zone.
On the Welcome to the New Zone Wizard page, click Next.
On the Zone Type page, click Secondary zone, and then click Next.
On the Zone name page, type corp.contoso.com, and then click Next.
On the Master DNS Servers page, type DC1, and then press TAB. The wizard displays both the IPv4 and IPv6 addresses of DC1.
Click the 10.0.0.1 address, click Delete, and then click Next.
On the completing the New Zone Wizard page, click Finish.
In the console tree, click the corp.contoso.com domain. Note that it contains the records of the corp.contoso.com domain. The zone transfer was sent over IPv6 between DC1 and APP1.

If you are running the IPv6 test lab in a virtual environment, you can discard the changes made by these procedures by restoring the previously made snapshots of the VMs for all of the computers in the test lab. Alternately, if you would like return to this working configuration using IPv6-only, you can create a new set of snapshots before restoring the previously made snapshots.

To manually restore the configuration of the IPv6 test lab, perform the following procedure.

Restoring the IPv6 Test Lab

You can discard the changes made by these procedures by restoring the previously made snapshots of the VMs for all of the computers in the test lab. To manually restore the configuration of the IPv6 test lab, perform the following procedure.

On DC1, from the console tree of the DNS Manager snap-in, open DC1, then Forward Lookup Zones, right-click corp.contoso.com, and then click Properties.
Click the Zone Transfers tab, and then click Edit.
In Allow Zone Transfers, click Only to servers listed on the Name Servers tab, and then click OK.
On APP1, From the console tree of Server Manager, click Roles.
In the details pane, click Remove Roles.
On the Before You Begin page, click Next.
On the Remove Server Roles page, clear DNS Server, and then click Next.
On the Confirm Removal Selections page, click Remove.
On the Installation Results page, click Close, and then restart APP1.
